Herein, we disclose the first manganese-catalyzed hydrosilylation of alkynes featuring diverse selectivities. The highly selective formation of E-products was achieved by using mononuclear MnBr(CO)5 with the arsenic ligand, AsPh3. Whereas using the dinuclear catalyst Mn2(CO)10 and LPO (dilauroyl peroxide) enabled the reversed generation of Z-products in good to excellent stereo- and regioselectivity. Such a way of controlling the reaction stereoselectivity is unprecedented. Mechanistic experiments revealed the dichotomy of manganese catalysis via organometallic and radical pathways operating in the E- and Z-selective routes, respectively.

The [Mn(CO)4-x(L){Ph2P(Se)NP(Se)Ph2-κ 2Se}] complexes, where x = 1 for L = PPh3 and PMePh2, and x = 2 for L = Ph2PCH2CH2PPh2 (diphos), were synth

Photochemical reactions between (L = CO, PBu3, PEt3, P(OMe)3, P(OPh)3, PPh3) and alkyl halides (RX) yield both alkyl and halo complexes, and , in equimolar quantities.Kinetic and quantum yield studies suggest that these reactions proceed by a radical chain pathway involving CO dissociation from the dinuclear complex and metal-metal bond homolysis of the coordinatively unsaturated dinuclear intermediate.

Several oxoalkylpentacarbonylmanganese compounds RC(O)CH2Mn(CO)5 (R = Me, Ph, MeO) have been synthesized and investigated (IR, 1H NMR, mass spectra).They are thermo- and photo-labile and can be stabilized by triphenylphosphine substitution.Thus acetonylte
